APPARATUS FOR OPENING OUT CART'ONS.

Application filed June c,

To all whom it may concern:

Be it known that I, WILLIAM Rosa, a subject of the Kingof Great Britain, residing at Albion lVorks, Gainsborough, England, have invented new and useful Improvements in Apparatus for Opening Out Cartons, of which the following is a specification.

This invention relates to apparatus4 for opening-out and feeding, or removing, cartons, or the like, and for analogous purposes, and particularly for opening out and feeding, or removing to any required apparatus, or place, cartons which have seen scored and collapsed, tions haverbeen cut to form turnover fiaps (such as, for example, cartons for contain. ing `flaked soap, cereals, or the like) but the said invention may be employed for other purposes to which it is, or may be applicable.

In an apparatus according to this invention a magazine is supported in a vertical lposition (or in a position somewhat inclined fromthe vertical) on any suitable framework, or support, the said magazine being open at the top, a pile of cartons, in a flat, or collapsed, condition being deposited therein, ridges, or like supports, being provided at the bottom of the magazine to sup' port the cartons. l

An ejecting pusher is supported on a reciprocable ejector carrier, and is capable of movement in a guide, to push the lowermost of the cartons through a slot, or opening, at the lower part of the said magazine, and on to a platform, vertically lreciprocable in guides or the like means being provided whereby' the said platform, with the carton supported thereon, can be lowered, a pivot` ally supported retaining finger (or several such fingers) being caused to-retain the carton in position on the said platform, whilst it is being lowered. v

A pivotally supported bending finger (or a number of such fingers) is ,capable of being operated to bend down one, or more,'ofV

the turnover fiap portions at the endfof the carton nearest to the magazine, whilst the remainder of the turnover flap portions of the said end, are temporarily allowedto remain in their original position and, when the platform, with the carton thereon,lhas been vbrought to rest in its lowered position, a reciprocable tapered Slicer, or blade, is so operated, as to enter between the upper and or folded flat, and whose end por1 trated.

and push 1923. serial No. 643,740.v

the said Aportions awayY from each other and,

at, ,or about, the same time, the retaining finger (or fingers) and the .said bending finger (or fingers) will be removedrk from their bearing on the carton. p l

Suitably supported fiap-pieces,.or blades or equivalent members, are partially rotated by toothed gearing, or rother suitable means, soas to co-act with vthe aforesaid slicer, or blade, and turn up the side portions of the carton, from their original collapsed positions,-and cause the carton to be expanded and to assume the hollow, or tube-like, form required.

The slicer, or blade, is lthen caused to retire to a position clear of the expanded car ton whilst the' aforesaid flap pieces, blades, or the like, retain the sides of the said carton'in proper position.

The said platform is then caused to rise and carry the expandedcarton between the sides of a guidin element, supported above the platforman when the platform is in its highest position, with the expandedcartonbetween the .sides ofthe said guiding element,.a pushing, vor delivery,`element (or several such elements), lpreferably carried on the `same carrier as the aforesaid ejecting pusher and operated simultaneously therewith, are caused to engage with the end of the expanded carton, which is now in proximity tothe magazine, and by forward movement will push the carton off from the said platform and out of engagement with the said guiding' element, and onto a caseforming or othermachine, or on to a table, conveyorbelt, or other receptacle, or place' and, at the same-time, the aforesaid ejecting pusher ac-ts'to' deliver another flattened, or collapsed, carton from the magazine, and on to the platform, to be in turn dealt with as desired.

I` will describe with reference to the accompanying drawings how this invention can be performed, premisin'g that I do not limit myself to the precise details `illus- Figure l 4is aI side elevation, Figure 2 a plan, and Figure 3 an end elevation of an apparatus yconstructed in accordance with this invention. Figure 3 is drawn to a scale somewhat smaller than that to which `Figures Land 2 are drawn.

Figures 4 and 5 shew, in perspective,rde `110 tails as hereinafter explained,

A vertical vmagazine (indfcated at 1)is supported by any suitable means ffrom the framework 2 which may, for example, constitute part of a case-forming machine.

A pile of collapsed, or attened out cartons 3 is placed in the said magazine they being supported on ridges, or bars, 4, carried at the lower end of the magazine V1, by any suitable support.

An ejectring pusher 5 is carried by, and can slide upon the nbar 6, carried vin bosses 7 on theI framework 2, the said pusher 5 being operated by the cam 8, acting upon the .pivoted arm 9, connected by the link 10,

Vthe magazine through Vtheslot 12,*ben'eath the platform 13, which is secured to the upg and pins 11, and 11a, to the said pusher 5, so that it pushes the lowermost carton from the forward side of the magazine and on to per end ofa spindle 14, verticallyV reciprocable in the guide 15, on the framework.

`Anarm` 16Y is provided with a rollerA 17,

.y i l(bearing against the cam 21 under the action lof the spring 24) and is carried by and can be-osc'illated onra spindle 18, supported by the framework in bearings, oneof which, 19, isseenin Figure 1. The pivoted arm 9, is al'socarried onY the spindle 18, the roller 'l' 20ron the said arml bearing against the pe- Y rip'h'ery ofthe cam 8, under theV action of the spring 23connected to studs (one of which is` seen atl 23a) respectively on. the arm' 9 andthe framework. Motion is communicated from the roller-arm 16 to the platform 13 through the link 16a, joint pins 16h.

andj 1 6, motion arm 16d, link16?, pins 16f,

and'y 16g, and yoke 16h. 7 Y

The cams 21, and 8, are secured to the shaft 22'carriedY in aV boss 22a' and rotated by any suitable means, such for instance as a sprocket wheel and chain drivenrby the main shaft of the case forming. machine.

A retaining finger 25, is pivotally sup ported on a spindle 26, carried by a bracket work 2.

27, and a bending finger 28, also pivotally supported on the said spindle 26, is resiliently connected to the retaining finger 25, by means of a spring 29, connected at one end with theY stud 36, on the linger 28, and at the other end, with the stud 31, onv `the finger 25.

A stop 32 on the finger 25 limits the ei:- tent ofV movementY between the fingers 25 `and 28. Y

The bending. finger 28, is actuated by a cam33,'vthrough theniedium of an arm 34- carrying a rollerI 35, kept to its bearing on the cain by the spring 36, the link 37 and rjoint pins 38, and 38a connecting the arm 34 to the arm of the piece 28EL connected to the finger 28. Y Y

The arm 34 is oscillatably supported onza spindle 39, carried in a boss 40, onthe frame- The slicer, ory blade 41, is reciprocably supported on a rod 42, carried in bosses 43, Y

Von the framework 2 and the requisite move.

ments are imparted to the said slicer, or blade, from a cam 44, against which (under the pressure of the spring 49) bears the roller 45 the arm 46 being pivotally carried on the spindle18, andY connected by the link 47, and jointrpins 48 and 48a, to the part of the Slicer or blade which is carried by the rod 42. Y

The cam 33 is mounted on a rotatable shaft 50, toY which movement can be imstance, .as a sprocket-wheel and chain from the rotating main shaft of the case forming machine. v

A side blade, or flap-piece 51is capableV of partial rotary movement upon a spindle 52, carried in a boss 53. TheV requisite 'moveinentsrare imparted to the saidL blade, or flap-piece, from a cam 54, (whichinay be formed `in one with the cam 33 as shewn) against which cam, under the actionvof; a

spring 60, bears a roller. 58, carried" by the arm 57 which can oscillate on a spindle V5.9,

carried' in a boss 59a, on the framework 2. rlfhearm 57 carries, at top, a toothed sector 56, which engages a pinion 55, on the'spindle 52.

A hookfpin 61, is carried on the end of an, arm 62, formed in one with the boss of the pinion 55. Y

Vparted by any suitable means such, for in- Acorresponding side-bladel, or flap-piece 51a, is capable of partial rotary movement,u

.on al spindle. 63, carried in a boss 64.

Pivotallycarried, by a pin 65, on arde-V pending lug 65a- (attachedto, o r integral with, the side-bladela) is a hook-piece 66,'

the outer end, or hook-proper 67, of which v caii'be engaged by thehook-pin61, the y spring 68,V retaining the hook-piece Y66,

against a stop'69, (formed on the depending., lug 59a)v in the` normal position relatively thereto as shewii in Figure 3.

A projection 7.0, on the web connectingV the two bosses, 7 and 64, Vis adapted to engage the side of the depending lug 65a, andV prevent the side-plate, or rflap-piece, 51?,

from [turning further to the right ,of the 1 form 13. 7

Adelivery pusher 7 3, operated by the arm9, and co-acting partswhich,'wlientthe platform13 is in ythe raised positionv and whenithe ejecting-pusher 5 isrpushing a col lapsed carton from the magazine, the said pusher 73,pushes the expanded carton ofi'V the platform 13 to the required place; for example onto the former (74) of a caseforming machine.

The apparatus is operated as follows A pile of collapsed, or flattened out cartons being contained inthe magazine 1 and supported therein by the ridges, or bars, 4, the ejecting pusher 5, is operated from the cam 8, and the lowermost carton is pushed thereby through the slot 12 onto the platform 13, which is then lowered by the action of the cam 21, and, at the same time, the bending finger 28, and the retaining finger 25, are operated so that the retaining finger 25 comes into contact with, and Vretains the said carton 3 on the platform 13, whilst the bending linger28 is actuated to bend down the turnover flap portions 3a and 3b of the carton 3, as shewn clearly in Figure 4, the portions 3c and 3d of the said carton at this time remaining in their normal, or original, positions.

The slicer, or blade, 41, is now operated from the cam 44, and enters -between the upperand lower-side portions 3d, and 3b, of the said carton, as also seen in Figure 4. At, or about, the same time the bending finger 28, is lifted away from the carton 3, and, when the said bending finger has moved upward a sufficient distance it comes against the stop 32, on the retaining finger 25, which is thereby also lifted out of contact with the carton.

The side blade, or flap-piece 51, is now operated from the cam 54, by means of the pinion 55, and toothed sector 56, and, the side of the carton 3 is raised to the position shewn in Figure 5, and the hook-pin 61, at the same time engages the hooked outer end 67, of the hook-piece 66, which is pivotally carried on the lug 65a of the side blade, or flap-piece, 51a. The side blade or flap-piece,

51 is preferably caused to move on its axis of rotation through an angle which somewhat exceeds 900, or a quarter of a circle, and, when the said side-blade, or flap-piece, 51,is in avertical position, as seen in Figure 5, the hook-pin 61, engages the hooked outer end 67 of the hook-piece so that any continued movement of the side-blade, or flap-piece 51, causes the side-blade, or flap-piece 51a, to bemoved to such position that more perfect bending of the corner portions of the now expanded, and tube-shaped, carton is effected.

The said side-blades, or flap-pieces 51, and 51, are now operated tol assume approximately vertical positions as shewn in Figure 5, and the slicer, or blade, 41 retires clear of the expanded carton. Whilst the said side-blades or flap-pieces, 51 and 51a, are temporarily held in their vertical positions, the platform 13, is moved upward and thereby the expanded carton is carried between the guiding side-pieces 71 and 71.

Whilst the platform 13 is retained for'ithe requisite time in its raised position, the delivery pusher 73 is operated to push the expanded carton from the platform 13, onto,

for example, the former 74 of a case-form- '(0 ing machine,'and at, or about, thesame time, the ejecting pusher 5', is opera-tedA to eject another collapsed or flattened, carton from the magazine 1, onto the platform 13.

As the hereinbefore described.sequencesv of operations of the several portions of the apparatus, are repeated, thev collapsed, or flattened, cartons will, in succession, be re-` moved from the magazine; be expanded and caused vvvto lassume a hollow, or ltube-like, shape, and be pushed from the platform 13,

to the required place; such, for instance, as

.onto a table, or onto a former of a case- .I

forming machine. f

I do not limit myself to the precise details hereinbefore described and illustrated as it will be evident that modifications may be made therein without departing from the nature of this invention.

What I claim is f 1. Apparatus for opening out cartons, having a vertically reciprocable platform to receive collapsed cartons, a pivotally supported nger and means for operating said finger to retain a carton on said platform while said platform is moved vertically; substantially as hereinbefore` explained.

2. The combination with apparatus in accordance with claim 1, of a second finger, means for operating said second finger to 100 bend down a flap portion of the end of a Y carton while it is held on the platform, a

lreciprocable slicer and means for causing said slicer to enter between the upper and lower portions of the carton and to push said portions apart while the finger which retains the carton on the platform and the finger which bends down the said flap portion on the carton aremoved away from the carton.

The combination with apparatus in. accordance with claim 1, of a reciprocable slicer and means for causing said slicer to enter between the upper and lower portions of the carton and to push said portionsV 115 apart, a pair of blades, means for partially rot ating said lblades so that the said portions of the cartons will be turned up thereby and opened out onv thek said platform will-be carried betweenr the sides Of said guiding element; substantially as hereinbefore de-V scribed.

5. The combination with apparatus in accordance with claim l, of a pushing element, a guiding element adapted tofcooperate with said vertically reciprocable platform when in its uppermost position and means for Operatingusaid pushing ele# ment so that the cartons will be pushed from the platform and from between the sides of said guiding element substantially as herein- Y before described.
